ABSTRACT
A comparative experimental study was conducted to evaluate the performance of
single cylinder four stroke VCR (variable compression ratio) diesel engine when fueled with
sunflower blends with diesel fuel (15/85 or 30/70 volumetrically). Tests were also carried out
with diesel fuel to be used as a reference point. Engine Power, Torque, BSFC, Thermal
efficiency, brake thermal efficiency (BTE) and Specific Fuel Consumption (SFC) were
recorded for tested fuel. These Investigations will help the nature in finding out the substitute
of Diesel and also maximize the use of refined sunflower oil blends with Pure Diesel in single
cylinder, four stroke VCR diesel engine. For these mixtures the operating Performance
Characteristics of single cylinder,4 stroke VCR diesel engine using blend of refined
sunflower oil at various loading conditions at constant speed are recorded and calculated to
compare it with pure diesel fuel.
KEY WORDS: Alternative Fuels, Blend, Refined Sunflower Oil, Engine Performance,
VCR Diesel Engine.
INTRODUCTION
Diesel engines have been use since the last 18th
century. Use of diesel in a CI engine
is a well proven technology. The first diesel engine was developed by Dr. Rudolf Diesel and

the use of plant oil as fuel for CI engine. Dr. Rudolf Diesel demonstrated his engine in Paris
in 1900 using peanut oil as fuel. The plant oil fuels were not accepted much at that time. It
was found that all the properties of plant oils were closed to diesel except viscosity and
volatility. Once the technology becomes widely known in the 1900’s the abundance and low
cost of fossil fuels caused a paradigm shift away from vegetable based fuels. At the turn of
current century, the same paradigm was beginning to shift back, due to rising fuel cost, the
environmental impact and an abundance of waste feedback engines. We have made an effort
in this paper to study the performance characteristics of blends of sunflower oil with diesel at
various ratios. The experimental setup consists of a single cylinder four stroke VCR diesel
engines coupled with electrical eddy current dynamo meter.
EXPERIMENTAL SETUP
Computerized single cylinder, 4 strokes, direct injection, water cooled VCR (Variable
Compression Ratio) diesel engine Test Rig is used. An engine indicator is fitted in control
panel which sense pressure and crank angle data interface with computer. The engine and
dynamo meter were interfaced to a control panel.
Performance Analysis Software “IC Engine Soft Ver. 8.5, Supplied by test rig
supplier” Apex Innovation Pvt Ltd ” was used for recording the test parameter such as fuel
flow rate, air flow rate, temperature, loads etc. and for evaluating the performance
characteristic such as Brake Thermal Efficiency, Specific Fuel Consumption, Indicated
Thermal Efficiency, Mechanical efficiency (ηmech), Volumetric Efficiency (ηvol) etc.
The calorific value and density of the particular fuel was fed to the software for
calculating the above said parameters. Sunflower refined oil is blended with petroleum diesel
in proportion like 15%, and 30%. These blends are termed as DSFB15, DSFB30. Engine
performance using these blends and pure diesel have been recorded and calculated in IC
engine lab at Moradabad Institute of Technology, Ram Ganga Vihar, Phase II, Moradabad,
Uttar Pradesh (India).

CONCLUSIONS
The sunflower refined oil with 15%, and 30% blend with petroleum diesel are used in
the computerized VCR diesel engine without any modification in engine or fuel system,
performance evaluation. It was observed that the Performance operating characteristics that
are Torque, Brake power, friction power, indicated power, brake thermal efficiency, indicated
thermal efficiency, specific fuel consumption, volumetric efficiency, and mechanical
efficiency is nearly equal to petroleum diesel at various loading conditions at constant speed
for sunflower refined oil blend with diesel at 15% (DSFB15) and 30% (DSFB30) oil blends.
Therefore, sunflower is a cheap raw material and its low operating cost in refining production
make this study a capable one for possible technological applications. Sunflower refined oil
blended with diesel fuel can be used as an alternative fuel in diesel engines without any major
modification.
